LONDON (MarketWatch) -- U.K. stocks fell Friday, with British Sky Broadcasting Group PLC losing ground as it agreed a deal to purchase assets in Germany and Italy, although stock in Royal Bank of Scotland Group PLC outperformed after the bank's financial update.

The FTSE 100 gave up 0.2% to 6,808, but was still on track for a weekly gain of about 0.8%.

BSkyB shares led decliners on the index, with a 4.4% pullback after the British broadcaster said it will pay 4.9 billion pounds ($8.3 billion) to buy Sky Italia and a 57.4% stake in Sky Deutschland from 21st Century Fox Inc.(NWS). The deal paves the way for BSkyB to create a pay-TV business across Europe.

But shares of Royal Bank of Scotland Group PLC leapt 10% as the company said it expects pretax profit of GBP2.65 billion for the first half of the year, compared with GBP1.37 billion in the year-ago period. Second-quarter net profit fell on charges.

Later in the session will be the first release of U.K. gross domestic product for the second quarter.
